LADDER ATTACHMENT.

Application filed June 15, 1922. Serial No. 568,567.

To all whom it may cancern:

Be it known that I, OLEF T. LARSON, a citizen of the United States, residin at Stoughton, in the county of Dane and tate of lVisconsin, have invented a new and useful Ladder Attachment, of which the following is a specification.

This invention has reference to ladder attachments and aims to provide novel means to be secured to the upper end of a ladder to permit the same to be readily and easily adjusted with respect to the building or wall against which the ladder is leaning.

Another object of the invention is to provide a device of this character which may be readily and easily positioned over a. rung, of a ladder, the device being constructed to-frictionally grip the rung. in a manner to prevent movement thereof. with respect to the ladder.

\Vith the foregoing and other object-s in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter (le-' scribed and claimed, it being understood that changes in the precise embodiment. of the invention herein disclosed. may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawing Figure 1 is a fragmental elevational view disclosing a device constructed in accordam-c with the invention as applied.

Figure 2 is a plan view of the attachment.

Figure 3 is a sectional view taken on line of Figure 1.

Figure 4 is a detail view disclosing the hook member that engages the attachment for holding the same to the ladder.

Referring to the drawing in detail. the

reference character 5 designates the upper portion of a ladder and the reference character 6 designates a run thereof.

The device forming the subject matter of the invention embodies a rod formed with right :angled end portions '2' that have their ends extended. inwardly as at 8 to provide supports for the rollers 9 which are secured thereto, as by means'of the pins 10.

The device includes a central portion 11 that has connection with the arms 12, as through the curved portions 13, which are curved to conform to the curvature of a ladder rung so that the same may be readily positioned over a ladder rung in a manner to frictionally engage the same.

A latch member ll is carried by the ladder and is designed to engage over one of the arms 12 of the device to secure the attachment against movement, and prevent the same from becoming displaced. From the foregoing it .will be seen that a ladder supplied with an attachment as described, may be readily and easily adjusted vertically with respect to the wall or building against which the same is supported. the rollers acting as anti-friction members.

It might be further stated that a ladder supplied with an attachment as described. may be used for supporting scaffolding. the end portions 7 of the rod acting to support the boards.

llaving thus described the what is claimed as new is The combination of a ladder support comprisin; a rod having intermediate its ends. an offset portion including curved rungengaging portions conforming to the curvature of a rung to secure the support to the ladder. laterally extending arms terminating in right angled end portions. rollers supported at the ends of the right angled end portions. said laterally extending arms engaging the side bars of the ladder to support said ladder in spaced relation with respect to an object. against which the ladder is positioned. and latch members pivotally connected to the ladder. and embracing portions of the laterally, extending arms to restrict movement ofthe support with respect to the ladder.

In testimony thatl clai'mthc foregoing as my .own. I have liei'ctdallixcd m signature in the presence of two witnesses.
